At Curie Dx, we believe busy families deserve quick, stress-free solutions for health concerns like strep throat, without the time, cost, and hassle of going in-person for a clinical visit. Our mobile app empowers you to confidently address health issues right from your phone by helping you send your healthcare provider the information they need to support your care. Created by a Johns Hopkins doctor, CurieDx helps you capture a clear throat photo and document the symptoms you are experiencing, then connect with a physician who can evaluate you and provide care. Here’s how CurieDx works in 3 simple steps: 1. Snap a pic of your throat. 2. In-app camera guidance helps you capture a clear photo, and a quick symptom questionnaire collects information on what you’re experiencing. 3. Connect with your doctor to share your photo and symptoms and give them the information they need to make an informed evaluation of your condition and prescribe care when they deem appropriate. No painful throat swabs. No crowded waiting rooms. Just help to provide the information your doctor needs to provide care, anytime, anywhere. Disclaimer: This app does not provide a medical diagnosis and does not substitute for professional medical advice, diagnosis, or treatment. CurieDx does not provide direct medical care. This app can help connect you to a licensed physician who can perform an independent assessment of your condition and prescribe care according to their independent clinical judgment. Always seek a doctor’s advice in addition to using this app and before making any medical decisions. If you think you may have a medical emergency, immediately call your doctor or dial 911.
